OVERVIEWThe 3Com® Wireless 7760 11a/b/g PoE Access Pointis a cost-effective dual band, Power over Ethernet(PoE) wireless solution for small and mediumenterprises. Configurable, this access point can operateat iEEE 802.11a or can be used as an iEEE 802.11b/gaccess point.

With the latest advanced security features such as Wi-Fi Protected Access (WPATM/ WPA2TM), WiredEquivalent Privacy (WEP) and Open system thisaccess point (AP) provides ultra-fast speeds of up to108 Mbps in turbo mode and offers superior long-range connectivity with eXtended range (XR)technology. This new access point also providesmultiple ssiD support and VPN passthrough alongwith VlAN support.

KEY BENEFITSENABLE WIRELESS FREEDOMTake advantage of the freedom of high-speednetworking without wires with this Wi-Fi CERTiFiEDTM

3Com Wireless 7760 11a/b/g PoE Access Point. WlANsare an attractive solution for cost-effectively andsecurely extending mobile access to wired networkresources and for creating full-featured networks insmall to medium businesses, remote sites or attemporary locations. Each access point supports upto 64 wireless users, allowing plenty of room for growth.

PROVIDE POE DEPLOYMENT FLEXIBILITY PoE support makes it easier than ever to overcomeinstallation problems by eliminating the need for anAC power plug at each AP. Power the AP with any

3Com PoE switch or other 802.3af-compliant PoEproducts supply both power and data to the accesspoints through Category 5 or 6 Ethernet cable, givingyou flexible installation options in hard-to-wire or -reach locations.

SECURE AND PROTECT WIRELESSCOMMUNICATIONS3Com delivers enterprise-class security features tosmall and medium businesses. To shield wirelesscommunications at the source, WPA2 with AEsencryption provides the latest, toughest standards-based security—WEP encryption supports legacywireless clients. For additional protection, thisaccess point supports iEEE 802.1X and MAC addressaccess control, authentication, and authorizationthrough backend RADiUs servers.

PROVIDE FLEXIBLE SECURITY AND ACCESSCONTROL supports up to four ssiDs with different securityprofiles for groups of users. iEEE 802.1Q-compliantVlAN support works with the multiple ssiD feature tocontrol access to network resources and segmentuser traffic.

UPGRADE TO WORK WITH 3COM’s ENTERPRISEGRADE WIRELESS CONTROLLERS OFFERSINVESTMENT PROTECTIONAs your network grows, this AP 7760 can be convertedto a managed AP to work with the 3Com WX 3000series Unified Controller, the WX 5000 series Wirelesscontroller and the s7900E wireless controller blade.
